API-first Development with OpenAPI
REST APIs are everywhere but keeping them organized and consistent can be very difficult, especially as APIs grow and teams change. Do we write a bunch of code and then document it and hope we were accurate? Do we write a bunch of markdown documents describing the ideal API before coding starts and hope that we got it right? How do we communicate these changes over time to the people using our API?
Instead, let's explore how the OpenAPI specification (formerly called Swagger) can help us with an API-first approach. In this talk we'll learn what problems OpenAPI was designed to solve, how to use it to make your REST APIs more consistent, and how we can use it to make our development process a lot simpler. Once we know the basics, we'll use it to create our own API, validate that it is consistent, and generate not only server code but clients in multiple languages. At the end of this talk, you'll know what kind of problems OpenAPI solves, and how to use it to make your REST APIs sing!
An Introduction to JDK Flight Recorder
Did you know that the Java Virtual Machine comes with a built-in high quality performance and diagnostic tool that has almost zero overhead? Come learn about the JDK Flight Recorder (JFR), a tool that provides high quality diagnostic and performance information about what’s going on inside the JVM and your code. We’ll go over what JFR is, how to use it, and work through several live examples. By the end of this talk, you’ll know how to use JFR to help solve performance problems, debug your code, and how to add your own metrics.
Java Cram Session: Get Caught Up on the Latest Java Changes
Let’s get caught up with the latest Java developments! Java is changing faster than ever, and it can become overwhelming to catch up. In this talk, we’ll go over the most important features you’re likely to use as a professional developer. You’ll learn what the new changes are, why you’d want to use them, and how to use them. This talk will cover changes starting with Java 9 and going all the way to the latest release. We will cover syntax changes, changes to the Java Virtual Machine, and changes to how Java is packaged and distributed. While that might seem like a lot, we’ll focus on the most essential parts to get you caught up without being overwhelmed. You don’t have to be a Java 8 developer forever. At the end of this talk you’ll be ready to start using all the great new features Java has to offer.
An Introduction to Kotlin
Kotlin has been catching on lately as an alternative to Java because of its null safety guarantees, type inference, cross-platform support, and ease of use with Android and Spring. Not to mention the fact that it is fully interoperable with Java. Is this something you and your team should considering spending time to learn?
Come to this session for an overview of Kotlin intended for Java developers (don't worry if you don't know Java, Kotlin is very easy to learn!). We will go over the major language features, syntax, and the Kotlin ecosystem so you'll know enough to make your own decisions by the end.
You will come away from this session with enough knowledge to decide if this is something you and your team should consider adopting.
Turbocharged Enterprise Development - Write Your Own Spring Boot Starter
You’ve managed to bust your monolith into Spring Boot microservices, but you’re not delivering features any faster. Adding new services takes just as long as before! All of this code is different, your APIs are all different, and each requires its own special configuration! What’s the deal?
One of the great features of Spring Boot is its Starters - dependencies referenced once in your build and Spring does the rest. In this talk we’ll learn what makes Spring Boot tick, and how you can put its Magic Sauce to work for your enterprise. We will build our own Spring Boot Starter to get our projects off the ground quicker and behaving the same way at runtime.
You’ll be happy because the mundane boilerplate work will be gone. Your boss will be happy because you can focus on features that deliver value. And your operations team will be happy because all your microservices can be treated the same way.
You will learn what a Spring Boot Starter is, how to write and deploy one, and some tips for how to make the developers on your team more productive as a result.
Beyond JUnit - Pragmatic Ways to Increase Code Quality
You and your team are writing and running unit tests, great! Better yet, they pass (most of the time)! But can you do more to ensure the quality of your code? Come to this talk where you will learn some practical new skills to help increase the quality of your code and catch bugs early in the development cycle. This will be a balanced look at different testing styles and tools. At the end of this talk, you will have several new techniques to bring to your codebase that will ultimately make your customers happy. This talk is aimed at Java developers who have some basic testing knowledge and want to move to the next level.
Write Better Spring Boot Code
Lots of organizations are using Spring Boot, but are we using it to its full potential? With such a large framework, it’s easy to overlook features or write code you don’t have to. In this talk, you will learn how Spring Boot works and how to write less code that does more work for you. This talk is aimed at Java developers who use Spring Boot and want to learn more.
Spring Boot is seemingly everywhere but not everybody is taking advantage of all it has to offer. Because it is such a large framework, it’s easy to overlook powerful features. Despite how well documented it is, doing the right thing can be confusing with so many tutorials and development styles on the internet. Come to this talk and learn the basics of what makes Spring Boot work, and how to use it more effectively. Learn real-world skills that you can put into production tomorrow. Your apps will be smaller, more idiomatic, and better tested.
